mixed XML serialization

[andrewcw]

I have an object that serializes back and forth.
I would like to have some objects not serialize ..and when
I read that info back into the class, have this item be
null ( or something like it ).

I modified a class I made by XSD.exe by adding these
values ( drvltr, disknum) , but I found when I wrote the
class out to file and retrieved it, the values were
persisted.

If this is reasonable, how do I approach it ? Thanks

In the example below, the tool inserts the declaration
[System.Xml.Serialization.XmlAttributeAttribute()]
for each attribute. Therefore I added the the attributes
drvltr and disknum because I reasoned maybe without the
declaration, they would be ignored.

[System.Xml.Serialization.XmlAttributeAttribute()]
public string uniqueid;
public string drvltr;
public string disknum;

Hi Andrew,

To exclude a field of a class when serializing, you can add the following
attribute before the declaration of this memeber variable. For example, if
you don't want "disknum" to be serialized, you can try the following code:

[System.NonSerialized()]
public string disknum;

This attribute only affects on the declaration of "disknum", and will be
ignored on latter fields.

Does this answer your question? If anything is unclear, please feel free to
reply to the post.

Thanks - that is exactly what I needed to know !!!

Hi Andrew,

Kevin, something is not right, I modified the class file
and it wrote out the fields and read them back in:
here's what that portion of the class now reads: { What
could be the cause of that ??? } THANKS

<snip>

Use the "XmlIgnore" attribute on the field. The XmlIgnore attribute
refers to XML serialization, whereas the NonSerialized attribute refers to
binary serialization.

Regards,
Dan

Thanks - I tested that and it worked:
[XmlIgnoreAttribute]
public string disknum;

Thanks, Daniel.

Andrew, apologize for my mistake.
